ABSTRACT
Black carbon (BC) is a major fraction (up to 35%, depending on methods used) of
soil organic carbon (SOC) in some of the most fertile and extensively cropped soils
of the world (Mollisols, Andisols, Terra Preta de Indio). Although BC is produced via
biomass burning in many ecosystems, it accumulates as a component of SOC in only
a few. Soils enriched in BC are not necessarily found in areas with the highest fire frequencies (savannah) or with the largest black carbon production (woody vegetation).
